In all cases a fixed constraint was applied at either end of the D6 brace. The hydrophone is constrained within the surface of the hole (surface-to-surface contact) to allow for movement within the hole but disallowing penetration; the area of the hydrophone that was linked to the D6 brace via welding has been constrained to the surface of brace D6 (using surface-to-surface gluing). This gluing represents the welding between the hydrophone and the surface of brace D6.

The beam-placing operates in two ways depending on where beams are delivered. On one condition, that beams are delivered on the ground level, lifting trolley will pick them up directly by both ends. On the other condition, that beams are delivered at abutment, by two trucks or other carriers at each side, the front trolley will pick up the front end of beams, then the front end of beams will be released from carrier; the front trolley moves forward, simultaneously with another carrier and beams, until the rear end of beams are at the same horizontal position of the rear trolley. The rear trolley will pick up the rear end of beams then, and once again the beams will be released from carrier. After the trolley getting the beams at deck level, the latter will be placed onto the bearings. To be specific on position control, trolleys move along the main girder/ main truss, and at other direction main girder/ main truss and move perpendicularly to span, and vertical position can be handle by trolley themselve by adjusting length of wires.

The FHWA has recommendations for new designs and existing construction. Some of the recommendations for new designs are: Use continuous spans rather than simply supported spans; this will reduce the need for expansion joints and thus minimize the potential for span separation. A side benefit of this practice will be a reduction in joint maintenance costs. And, use earthquake-protective systems (e.g., seismic isolation), where appropriate, to minimize the seismic demand on bridge members.

Structural approaches may also be necessary to protect coastal areas. Preparedness includes the education of populations. People need to know the dangers and what they can do to avoid them. In Florida, evacuation routes have been prepared and cyclone shelters are clearly signed and posted. Planning includes land-use planning. This regulation is used to reduce the vulnerability of people and property so for example, only low value land uses (recreational) can occupy coastal strips, the areas most vulnerable to a storm. In Northeast Florida, coastal properties have been rallied above the ground on stilts and have non-residential functions on the ground (storage). This means that hazards like the storm surges do not impact the people and less damage occurs to infrastructure.

The original walkway was designed to have single load bearing rods that would pass through the fourth floor walkways supporting beams, be supported with nuts and washers and hang the second floor walkway beneath as shown in the “Original Detail” in figure 1 . Due to a late design change for apparent manufacturing issues, the change was quickly implemented to the “As Built” design shown in Figure 1.

Rip-rap, though it is expected to have a long life-span as well, the issue of scouring taking place around the rip-rap adds significant cost given that eventually, the rock pile would need to be replaced every 2 years or so. A pier that requires 50 cubic meters of rip-rap would require 132 tons of concrete rubble - costing nearly $300 per replacement. With this data we are able to compare the present worth of the repair-and-replacement cost of Rip-Rap and Scouring ramps over the span of a 32

Beam end retaining clips, called BERC clips, attach to the end of main runners or cross tees and slip over the vertical flange of the wall angle. Install BERC clips when using 7/8" and 9/16" wall angles in seismic zones D, E, and F. BERC clips can be screw attached to the suspension members to prevent movement or not screwed to allow lateral movement of the suspension members. The BERC2 clip shown in Figure 8 allow up to 2" of movement. BERC clips serve the same purpose as stabilizer bars by keeping the perimeter of the ceiling system intact during an earthquake. BERC clips provide an alternative method to the stabilizer bar and install during the grid installation as shown in Figure

The idea of a tracked solution came about as a way to reduce the use of the hoist and its dangers as well as reduce the number of operators necessary to run this machine. While these things are achieved, a new set of issues arose leaving the need for further refinement. The interior of the PT20 is quite tight, leaving little room to make adjustments to the workpiece. Using the Sliding Rack would not only improve the ease of loading, but the holding ability of the machine as well. The current vice system is optimized for long pipe sections whereas the new and more adaptable rack system would allow for the proper mounting and machining of accessories. The supports mounted in the center of the rack bear the weight of the workpiece and serve as an adjustment point to ensure the face of the workpiece remains perpendicular to the insertion axis. The interlocking jaws on the face and rear of the rack are to ensure the workpiece is locked into place horizontally. The original design of the concept had two chucks in place of these jaws, but after feedback from the sponsor jaws were added to reduce the weight of the mechanism as well as to increase the ease of loading and

It also features 8 padded poles that offer its users the maximum level of safety.

These total soil resistances at each depth are calculated according to the aforementioned procedures from the soil spring lateral forces (P-y) extracted at depths -6.1m, -9.75m, and -12.19m as shown in Figures 8(b) to (d), respectively. It is observed that little bit time after the barge impact on the Pier-1, the inertial force is mobilized with a positive value sooner than soil resistances. Afterwards, when it reaches a negative value between 0.2s to 0.85s, it means that the pier inertial force is mobilized in the same direction as that direction of the applied impact load. During this period of time, the soil lateral resistance is mobilized as a major resistance source of the pier against the sum of barge impact and the added inertial forces. Since the pile cap+seal of Pier-1 has been surrounded by the soil, it is seen that resistance provided at this depth (i.e. depth of -6.1m) is more than those in depths below. In Figure 8(b), once the lateral resistance of soil is fully mobilized at 20mm with a corresponding ultimate lateral resistance 35.4kN (Pu=35.4kN), it is yielded up to the plastic state during the loading process. Figures 8(c) and (d) show the mobilization of soil spring at the depths -9.75m and -12.19m which had the peak values approximately Pu=17.58kN and Pu=15.16kN with displacements about 15.94mm and 11mm in the positive direction (+y), respectively.

The issue at hand is whether or not the repairs and maintenance to the wharf are deductible under the Income Tax Act 2007 (ITA). Repairs and maintenance are allowable deductions under section DA 1 ITA, however, the deductibility is reliant on whether or not the fact situation meets a two-stage test which the Inland Revenue Department (IRD) has outlined in an Interpretation Statement: IS 12/03.

These are used to stop the capture falling rocks before they cause risk to the structure. They are usually constructed along the transportation routes.

Top tensioned risers (TTRs) are risers used for dry tree production facilities like Spars and tension leg platforms (TLPs) as conduits (either for production, drilling, injection or export) between the floating production units (FPU) and subsea systems. ‘A top tensioned riser extends substantially vertically from a platform hull to the sea bottom. The riser includes length adjustment at its upper end and is detachably connected to an anchor pile at its lower end.’(Jordan et al., 2006). TTRs are tensioned at the top to resist environmental loading. The tensions needed for the production risers are generally lower than those for the drilling risers (Chakrabarti, 2005).
